Handsome and easy-going, Tropaeolum majus (Nasturtium) is a popular annual or short-lived perennial with creeping or sprawling stems that command attention in any landscape. Blooming from winter through spring in mild winter areas and from summer to fall in colder climates, Nasturtium boasts a profusion of long-stalked, funnel-shaped flowers, about 2-3 in. wide (5-7 cm), ranging in color from creamy white to orange, mahogany, red, and yellow. The blossoms may be single or double and have an unusual and refreshing fragrance. They stand out against the pretty foliage of rounded, parasol-like leaves.

  • Nasturtium is perennial in hardiness zones 9-11 and grown as an annual plant elsewhere.
  • Nasturtium can grow up to 1-10 ft. (30-300 cm), depending on the variety. There are both climbing and dwarf bush types.
  • The dwarf types, from 12 in. tall (30 cm) and 2 ft. wide (60 cm), are great selections for beds and borders, rock gardens, edgings, ground covers, or in mass plantings.
  • Climbing Nasturtiums, up to 6-10 ft. tall (180-300 cm), can quickly cover fences, banks, or stumps.
